Answer:
90
Explanation:
The mass number of the missing daughter nuclei can be obtained as shown in the attached photo.
No work is done because the object needs to be moved. The formula for work is Work = Force x Distance.
Answer:
4.25 J
Explanation:
Given that
mass of plastic ball = 11 g
Mass of plastic ball = 0.011 kg
velocity of ball = 29 m/s
We know that from work power energy theorem

We know that kinetic energy of moving mass given as

Now by pitting the values


KE= 4.25 J
So the work done on the ball is 4.25 J
